User interface for a keyboard, keypad, or touchscreen



The sole drawing FIGURE is a front view of a user interface for a keyboard, keypad, or touchscreen showing my new design.

The design shown consists of the appearance, shape, arrangement, and relative placement of the layout in a flat plane with no depth or contour.

The evenly spaced horizontally parallel broken lines shown in various locations indicate a change in color.

The broken lines shown that illustrate alphabetic characters are superimposed on a continuous surface and the dot-dash broken lines are directed to environment and are for illustrative purposes only; such broken lines form no part of the claimed design. 

The ornamental design for a user interface for a keyboard, keypad, or touchscreen, as shown and described.
